These books are different from such other books available in the market in many ways. Besides making the model simple and practical, we have, for the first time, provided illustrated printed papers, complete with all foldlines and symbols, in the pocket of the back inside cover. In addition to explaining how to make a model, useful information has been provided about it. For example, we have given information about the habitats and food habits of the birds and animals and many other amazing facts about the things along with their model. These books will help in the mental development of children and they become creative. Simple step-by-step folding instruction with clear, informative diagrams.
